Diamond Drills

Diamond Drills

Diamond core drill bits with 1/2 gas connection are diamond tools used for drilling marble, stone, granite, quartz, porcelain stoneware, stone materials, and sintered materials such as Laminan, Lapitec, Kerlite, and Dekton. These drill bits are applied to Computer Numerical Control (CNC) machines to execute precise, high-quality holes. The choice of drill bit depends on various factors, including the type of hole to be drilled (through-hole or blind hole), the material to be worked on, and the desired diameter. There are different types of professional drill bits available: electroplated diamond, sintered, and brazed solder, all suitable for through-hole drilling and meeting various drilling needs. Instead, for creating blind holes, universal shank drill bits with a diameter of 10 mm are used.

Types:

  • Electroplated diamond core drill bits: ideal for marble, travertine, stone, and glass. They offer high cutting speed and good surface finish.
  • Sintered diamond core drill bit: suitable for granite, hard stones, abrasive stones, and quartz. It ensures greater durability and resistance to wear.
  • Diamond core drill bits for porcelain stoneware: designed to drill all types of ceramic materials, porcelain stoneware, and ceramics. They offer high precision and impeccable finishing.
  • Thin-wall diamond core drill bits: the next-generation thin-wall diamond core drill bits ensure high feed rates in drilling granite, quartz, and porcelain stoneware. Their thin structure allows for precise and clean holes.

How to use drill bits:

  • The drill bit easily attaches to the drill chuck of the CNC machine thanks to the universal 1/2 gas connection.
  • Cutting parameters: it is important to follow the manufacturer's instructions regarding rotation speed and feed rate in the Z-axis to achieve optimal results and extend the tool's lifespan.
  • Coolant: the use of water is essential as a coolant during drilling to reduce overheating of the diamond drill bit, promoting greater durability and a better finish of the hole.
  • The amount of water depends on the diameter of the drill bit.

Recommendations:

  • Type of hole: through holes or blind holes require different types of cutters.
  • Material to be drilled: the characteristics of the material determine the choice of the type of diamond (electroplated, sintered, brazed or for porcelain stoneware).
  • Hole diameter: a wide range of diameters are available to meet different requirements.
  • The speed of rotation must be adapted to the diameter of the drill hole.

Types of diamond drills:

  • Electroplated diamond drills: ideal for marble, travertine, stone and glass. They offer high cutting speed and a good surface finish.
  • Sintered diamond core drills: suitable for granite, hard stone, abrasive and quartz. They guarantee a longer lifetime and greater wear resistance.
